Description

Technical Field

[0001] The present invention relates to the field of sewage treatment equipment, and in particular to an organic wastewater sewage treatment device and a treatment method thereof. Background Art

[0002] Organic wastewater mainly comes from domestic sewage and industrial fields such as food processing, papermaking, pharmaceutical, and chemical industries. This type of wastewater is characterized by high organic matter concentration, complex composition, high chromaticity, and accompanied by peculiar smells. It often contains suspended solids, grease, proteins, and toxic and refractory organic substances, which have potential pollution and pose a threat to the environment. Therefore, it is necessary to effectively treat organic sewage wastewater to avoid environmental pollution. When treating organic sewage, large particles, suspended solids, and grease are usually removed through pretreatment, and then biological or chemical methods are used to remove organic substances. Further deep treatment is carried out to remove refractory organic substances, nitrogen, and phosphorus, etc., to meet higher discharge standards or reuse requirements. During the process of removing organic substances, impurities in the sewage are prone to concentrate and accumulate, which will reduce the transfer of oxygen, thereby reducing the dissolved oxygen content in the water, and affecting the mixing with biological fillers and oxygen, being unfavorable for the growth of microorganisms, and affecting the decomposition of organic substances. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the present invention provides an organic wastewater sewage treatment device and a treatment method thereof, effectively solving the problems mentioned in the above background art.

[0005] An organic wastewater sewage treatment device includes a housing and a box body located at the top of the housing. Inside the box body, a first feeding channel, a mixing chamber, and a second feeding channel are sequentially arranged from left to right. Partition plates are fixedly connected between the mixing chamber and the first feeding channel and the second feeding channel on both sides respectively. Filter plates are fixedly connected to the inner sides of the partition plates. Scrapers that can rotate synchronously are rotatably connected to both ends of the filter plates respectively. A plurality of air outlet pipes are fixedly connected to the lower side of the surface of the mixing chamber. An air inflation device is arranged on the lower side of the box body. The air inflation device is connected to the plurality of air outlet pipes, and check valves are respectively installed at the connection ends. A plurality of packing rods that can swing synchronously are rotatably connected inside the mixing chamber, and a structure in which the packing rods swing reciprocally synchronously can be formed when the air inflation device inflates the mixing chamber.

[0006] Furthermore, a trapezoidal frame is fixedly connected to the left side of the box body, and a plurality of filter holes are formed on the surface of the trapezoidal frame.

[0007] Further, a plurality of planes with gradually increasing heights from left to right are arranged on the trapezoidal frame. Sliding grooves are respectively formed on the surfaces of the planes, and push plates capable of reciprocating up and down are respectively slidably connected to the inner sides of the sliding grooves. The bottoms of the plurality of push plates are fixedly connected to each other. Whenever the push plate moves upward, the top of the push plate is flush with an adjacent plane. A plurality of key-shaped holes are formed on the surface of the push plate.

[0008] Further, the inflation device includes inflation cylinders arranged corresponding to each other left and right. The inflation cylinders are fixedly connected to the inner wall of the housing. Piston plates are respectively axially slidably connected to the interiors of the inflation cylinders. The middle parts of the piston plates are respectively fixedly connected with piston rods. The piston rods are respectively slidably connected to the bottoms of the inflation cylinders. Moving racks are respectively fixedly connected to the inner sides of the two piston rods. A reversing gear is meshed between the moving racks. The reversing gear is fixedly connected to the inner wall of the housing. A driving device for controlling the reciprocating up and down movement of one of the piston rods is arranged on the front side of the inflation cylinder;

[0009] The upper ends of the inflation cylinders are respectively fixedly connected and communicated with air guide pipes. The other ends of the air guide pipes are respectively fixedly connected with second three-way pipes. The other two interfaces of the second three-way pipes are respectively fixedly connected with an intake check valve and an outlet check valve. The other ends of the two outlet check valves are jointly fixedly connected with a first three-way pipe. The lower ends of the vertically arranged check valves are jointly fixedly connected with a first communication pipe. A second communication pipe is fixedly connected and communicated between the plurality of first communication pipes. The upper end interface of the first three-way pipe is fixedly connected and communicated with the second communication pipe.

[0010] Further, a plurality of connecting rings are respectively arranged in sequence from left to right inside the mixing chamber. The front and rear ends of the connecting rings are respectively fixedly connected with support rods. The two ends of the support rods are respectively rotatably connected to the inner wall of the mixing chamber. Filler rods are respectively fixedly connected to the lower ends of the support rods. Connecting gears that mesh with each other are respectively fixedly connected to the surfaces of the connecting rings. Under the meshing transmission of the connecting gears, the plurality of support rods swing reciprocally at the same time.

[0011] An organic wastewater sewage treatment method includes the following steps:

[0012] S1. Start the first motor, and control the synchronous rotation of the scraper on the surface of the filter plate through the first motor;

[0013] S2. Start the second motor, drive the plurality of support rods to swing reciprocally through the second motor, and drive the lower filler rods to swing in a wavy shape when the support rods swing reciprocally; meanwhile, drive the inflation device to continuously aerate the inside of the mixing chamber through the second motor to increase the oxygen content of the sewage; while the inflation device is working, drive the push plate to continuously reciprocate up and down;

[0014] S3. Sewage enters through the first feed cylinder and flows out through the second feed cylinder. The trapezoidal frame filters out a large amount of large particulate impurities. Then, during the reciprocating up and down movement of the push plate, the large particulate impurities are removed. The sewage that enters the box body is stirred into a vortex by the scraper, fully mixed with the packing rods and oxygen. The aggregated particles filtered by the filter plate are crushed under the rotation of the scraper and are fully mixed with the packing rods and oxygen under the mixing of the scraper, realizing sewage denitrification and decomposing the organic matter in the sewage.

[0015] The structure of the present invention is novel, ingeniously conceived, and simple and convenient to operate. Compared with the prior art, it has the following advantages:

[0016] 1. Under the rotation of the scraper, the sewage can be stirred to promote the mixing of the sewage and the biological packing rods. And under the rotation of the scraper, large particulate impurities and aggregated impurities can be broken, making them fully mixed with the sewage;

[0017] 2. Through the aeration equipment, air can be continuously aerated into the mixing chamber through the air outlet pipe, strengthening the oxygen content of the sewage in the mixing chamber and improving the effects of sewage denitrification and decomposing the organic matter in the sewage;

[0018] 3. Multiple packing rods that can swing synchronously are arranged inside the mixing chamber. They can not only provide a carrier for the attachment and growth of microorganisms, but also form a wavy swing, which can cut and block the bubbles, increasing the dissolved oxygen concentration in the sewage and strengthening the transfer of organic matter and dissolved oxygen by microorganisms;

[0019] 4. After the large particulate impurities are blocked outside by the trapezoidal frame, through the reciprocating up and down movement of the push plate, the large particulate impurities can be continuously pushed to the upper plane, and then gradually transferred to the upper end of the trapezoidal frame, facilitating the transfer of large particulate impurities, avoiding blockage of the trapezoidal frame, and improving the sewage flow effect.

Detailed implementation manners

[0033] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0034] As Figures 1-12 shown, the present invention provides an organic wastewater treatment device, which includes a housing 1 and a box body located at the top of the housing 1. Inside the box body, a first feed channel 2, a mixing chamber 3, and a second feed channel 4 are sequentially arranged from left to right. Sewage enters through the first feed channel 2 and flows out through the second feed channel 4. The mixing chamber 3 is used to mix the sewage with the biological filler rods 48. Partition plates 5 are fixedly connected between the mixing chamber 3 and the first feed channel 2 and the second feed channel 4 on both sides respectively. Filter plates 6 are fixedly connected to the inner sides of the partition plates 5 for filtering large particle debris and aggregated impurities. Both ends of the filter plate 6 are rotatably connected to scraping plates 7 that can rotate synchronously. Under the rotation of the scraping plates 7, the sewage can be agitated to promote the mixing of the sewage with the biological filler rods 48, and large particle impurities and aggregated impurities can be broken under the rotation of the scraping plates 7 to make them fully mixed with the sewage. A plurality of air outlet pipes 32 are fixedly connected to the lower side of the surface of the mixing chamber 3. An aeration device is arranged on the lower side of the box body. The aeration device is connected to the plurality of air outlet pipes 32 and check valves 33 are respectively installed at the connection ends. The check valves 33 are used to prevent the sewage from flowing back into the aeration device. Through the aeration device, air can be continuously aerated into the mixing chamber 3 through the air outlet pipes 32 to enhance the oxygen content of the sewage inside the mixing chamber 3 and improve the effect of sewage denitrification and decomposition of organic matter in the sewage; A plurality of filler rods 48 that can swing synchronously are rotatably connected inside the mixing chamber 3. When the aeration device aerates the mixing chamber 3, a structure in which the filler rods 48 swing reciprocally synchronously can be formed. During the reciprocal swinging of the filler rods 48, not only can the mixing effect with the sewage be improved, providing a carrier for the attachment and growth of microorganisms, but under the action of oxygenation and water flow, the microorganisms will multiply continuously. The filler provides a fixed attachment place for the microorganisms, and the filler rods 48 form a wavy swing, which can improve the cutting and blocking effects on bubbles, increase the dissolved oxygen concentration in the sewage, strengthen the transfer of organic matter and dissolved oxygen by microorganisms, and the filler rods can be backwashed and cleaned and recycled without disassembly, reducing the maintenance cost.

[0035] A trapezoidal frame 49 is fixedly connected to the left side of the box body. A plurality of filter holes are formed on the surface of the trapezoidal frame 49. The filter holes are used to filter large-particle debris to prevent large-particle debris from entering the box body and affecting the sewage treatment effect. Further, a plurality of planes with gradually increasing heights from left to right are arranged on the trapezoidal frame 49. Sliding grooves 53 are respectively formed on the surfaces of the planes. Push plates 50 capable of reciprocating up and down are respectively slidably connected inside the sliding grooves 53. The bottoms of the plurality of push plates 50 are fixedly connected to each other. Whenever the push plate 50 moves upward, the top of the push plate 50 is flush with an adjacent plane. A plurality of key-shaped holes 51 are formed on the surface of the push plate 50. The key-shaped holes 51 are used for sewage to flow through. After the large-particle debris is blocked outside by the trapezoidal frame 49, the large-particle debris can be continuously pushed onto the upper plane through the reciprocating up and down movement of the push plate 50, and then gradually transferred to the upper end of the trapezoidal frame 49, which is convenient for transferring the large-particle debris, preventing the trapezoidal frame 49 from being blocked, and improving the sewage flow effect.

[0036] The inflation device includes inflation cylinders 27 arranged corresponding to each other left and right. The inflation cylinders 27 are fixedly connected to the inner wall of the housing 1. Piston plates 31 are respectively axially slidably connected inside the inflation cylinders 27. The middle parts of the piston plates 31 are respectively fixedly connected with piston rods 30. The piston rods 30 are respectively slidably connected to the bottoms of the inflation cylinders 27. Moving racks 28 are respectively fixedly connected to the inner sides of the two piston rods 30. A reversing gear 29 is engaged between the moving racks 28. The reversing gear 29 is fixedly connected to the inner wall of the housing 1. A driving device for controlling the reciprocating up and down movement of one of the piston rods 30 is arranged on the front side of the inflation cylinder 27. Driven by the driving device, one of the piston rods 30 is driven to move, and then, through the engagement and transmission of the connecting rack and the reversing gear 29, the piston rods 30 on both sides can be driven to reciprocate up and down alternately;

[0037] The upper ends of the inflators 27 are respectively fixedly connected and communicated with air guide pipes 40. The other ends of the air guide pipes 40 are respectively fixedly connected with second three-way pipes 37. The other two interfaces of the second three-way pipes 37 are respectively fixedly connected with intake check valves 39 and outlet check valves 38. The other ends of the two outlet check valves 38 are commonly fixedly connected with a first three-way pipe 36. When the piston rods 30 on both sides reciprocate up and down alternately, gas can be continuously absorbed into the inflators 27 through the intake check valves 39, and then pushed out to the first three-way pipe 36 through the outlet check valves 38. The lower ends of the longitudinally arranged check valves 33 are commonly fixedly connected with a first communication pipe 34. A second communication pipe 35 is fixedly connected and communicated between the plurality of first communication pipes. The upper end interface of the first three-way pipe 36 is fixedly connected and communicated with the second communication pipe 35. The gas enters the second communication pipe 35 and the second communication pipe 35 through the first three-way pipe 36, pushes open the check valves 33, and enters the mixing chamber 3 through the air outlet pipe 32, continuously aerating the sewage inside the mixing chamber 3, increasing the oxygen content of the sewage, promoting the activities of microorganisms, and accelerating the oxidation and decomposition of organic substances.

[0038] Further, a plurality of connecting rings 46 are sequentially arranged from left to right inside the mixing chamber 3. The front and rear ends of the connecting rings 46 are respectively fixedly connected with support rods 45. The two ends of the support rods 45 are respectively rotatably connected with the inner wall of the mixing chamber 3. The packing rods 48 are respectively fixedly connected to the lower ends of the support rods 45. The surfaces of the connecting rings 46 are respectively fixedly connected with meshing connecting gears 47. Under the meshing transmission of the connecting gears 47, the plurality of support rods 45 can swing reciprocally at the same time. When the support rods 45 swing reciprocally, the packing rods 48 can be driven to swing in a wave shape continuously. Under the meshing of the connecting gears 47, the plurality of support rods 45 swing synchronously, which is convenient for transmission and control.

[0039] The driving device includes a guiding column 12 rotatably connected to the inner wall of the housing 1. A limiting rod 26 capable of moving up and down is slidably connected to the lower end of the guiding column 12. A linkage plate 25 is fixedly connected to the lower end of the limiting rod 26. The linkage plate 25 is vertically slidably connected to the inner wall of the housing 1. A laterally arranged chute plate 42 is fixedly connected to the rear end of the linkage plate 25. A chute is provided on the surface of the chute plate 42 along the length direction. A rotating plate 43 is arranged at the rear side of the linkage plate 25. A second motor 41 is arranged at the rear side of the rotating plate 43. The second motor 41 is fixedly connected to the inner wall of the housing 1. The power output end of the second motor 41 is fixedly connected to the lower end of the rotating plate 43. A connecting pin shaft 44 is fixedly connected to the upper end of the rotating plate 43. The connecting pin shaft 44 is slidably connected to the chute. When the second motor 41 rotates, it can drive the rotating plate 43 to rotate. When the rotating plate 43 rotates, it can drive the chute plate 42 to move up and down through the sliding cooperation between the connecting pin shaft 44 and the chute. When the chute plate 42 moves up and down, it drives the linkage plate 25 to move up and down at the same time. The limiting rod 26 is used to improve the stability of the linkage plate 25 when it moves up and down by slidingly connecting with the guiding column 12. A connecting plate is fixedly connected to the rear end of the linkage plate 25. The other end of the connecting plate is fixedly connected to one of the moving racks 28. When the linkage plate 25 moves up and down, it can drive the corresponding moving rack 28 to move. Then, through the meshing of the moving rack 28 and the reversing gear 29, the piston rods 30 on both sides are driven to move up and down alternately, aerating the sewage in the mixing chamber 3. The lower end of the other connecting rack is fixedly connected to a linkage frame 52. The other end of the linkage frame 52 is fixedly connected to the bottom of the pushing plate 50. When the moving rack 28 moves, the pushing plate 50 is driven to reciprocate up and down through the linkage frame 52, synchronously transferring the large-particle sundries on the surface of the synchronous transfer trapezoidal frame 49.

[0040] A support rod 17 capable of swinging left and right is arranged above the guiding column 12. The middle part of the support rod 17 is rotatably connected to the inner wall of the housing 1. Both sides of the support rod 17 incline downward respectively. A swinging rod 19 is arranged at the upper end of the support rod 17. A connecting shaft is fixedly connected to the upper end of the swinging rod 19. The connecting shaft is rotatably connected to the surface of the box body and the rear end of the connecting shaft is fixedly connected to one of the swinging rods 19. The swinging rod 19 can swing reciprocally with the connecting shaft as the center; A baffle 21 is fixedly connected to the surface of the swinging rod 19. A pushing spring 20 and a sliding sleeve 18 are respectively sleeved on the surface of the swinging rod 19 below the baffle 21. The sliding sleeve 18 is located below the pushing spring 20. The upper end of the support rod 17 is hinged to the sliding sleeve 18. When the support rod 17 swings in one direction, it can drive the swinging rod 19 to swing synchronously through the sliding sleeve 18, and push the sliding sleeve 18 to move on the surface of the swinging rod 19 to compress the pushing spring 20. When the support rod 17 swings, the pushing spring 20 on the other side pushes the sliding sleeve 18 to reset;

[0041] Further, as Figures 4-6As shown, a top plate 15 is fixedly connected coaxially to the upper end of the guiding column 12. A guiding groove is formed on the surface of the guiding column 12. A telescopic shaft capable of moving up and down is slidably connected inside the guiding groove. When the telescopic shaft moves up and down, a structure for the guiding column 12 to intermittently rotate by 180 degrees is formed through the sliding cooperation with the guiding groove. When the guiding column 12 intermittently rotates, it can push the downward-tilted end of the support rod 17 upward to swing through the top plate 15. On the left and right sides of the upper end of the support rod 17, retaining rods 16 are respectively arranged. The retaining rods 16 are fixedly connected to the inner wall of the housing 1. The retaining rods 16 are used to limit the support rod 17 and control the swing amplitude of the support rod 17, so that the top plate 15 can push the support rod 17 to swing each time the guiding column 12 rotates. By controlling the intermittent swing of the support rod 17 through the guiding column 12, the effect of controlling the automatic swing of the packing rod 48 is achieved. The initial force generated during the intermittent swing of the packing rod 48 can improve the bubble-breaking effect and promote the mixing of sewage and oxygen;

[0042] Further, the telescopic shaft includes a buffer cylinder 22 and a guiding pin 23 that are slidably connected coaxially. A part of the guiding pin 23 is slidably connected inside the buffer cylinder 22. A return spring 24 is fixedly connected between the buffer cylinder 22 and the guiding pin 23. The return spring 24 is located inside the buffer cylinder 22. The end of the buffer cylinder 22 away from the guiding pin 23 is fixedly connected to the linkage plate 25; the guiding groove includes two arc-shaped grooves 13. A vertical groove 14 is formed between the two arc-shaped grooves 13. The upper and lower ends of the vertical groove 14 are respectively connected to the ends of the adjacent arc-shaped grooves 13. The depth of the arc-shaped groove 13 is greater than the depth of the vertical groove 14, and a slope surface is provided at the connection between the two ends of the vertical groove 14 and the arc-shaped groove 13. The slope surface is used to facilitate the guiding pin 23 to enter the vertical groove 14 through the arc-shaped groove 13. Since the depth of the arc-shaped groove 13 is greater than that of the vertical groove 14, when the guiding pin 23 enters the arc-shaped groove 13 and moves downward, the guiding pin 23 can drive the guiding column 12 to rotate by pushing the inclined surface of the arc-shaped groove 13. When the guiding pin 23 enters the vertical groove 14 from the arc-shaped groove 13, the guiding column 12 rotates by 180 degrees. When the guiding pin 23 moves upward along the vertical groove 14, the guiding column 12 is not affected. When the guiding pin 23 moves into the vertical groove 14, the return spring 24 is in a compressed state. After the guiding pin 23 moves to the upper end of the vertical groove 14, it re-enters the arc-shaped groove 13 under the push of the return spring 24, and then when the guiding pin 23 moves downward again, the engagement with the arc-shaped groove 13 drives the guiding column 12 to move downward again, achieving the effect of driving the guiding column 12 to intermittently rotate.

[0043] Inside the box body, an output shaft 9 is arranged axially. A receiving groove 54 is formed on the circumferential surface of the connecting ring 46 to provide an installation space for the output shaft 9. The output shaft 9 is respectively rotatably connected to the middle part of the filter plate 6 and the output shaft 9 is respectively coaxially and fixedly connected to the middle part of the scraper 7. A first bevel gear 10 is fixedly connected to the front end of the output shaft 9. A second bevel gear 11 is engaged with the front side of the first bevel gear 10. A gear shaft is fixedly connected to the middle part of the second bevel gear 11. The gear shaft is rotatably connected to the surface of the box body. A first motor 8 is arranged below the gear shaft. The first motor 8 is fixedly connected to the box body. The power output end of the first motor 8 is coaxially and fixedly connected to the lower end of the gear shaft. When the first motor 8 rotates, it can drive the gear shaft to rotate. Then when the gear shaft rotates, it drives the scraper 7 to rotate synchronously. The sewage is agitated by the rotation of the scraper 7, and the effect of controlling the scraper 7 to break large particle debris is achieved, which is convenient for the user to operate.

[0045] S1. Start the first motor 8 and control the scraper 7 to rotate synchronously on the surface of the filter plate 6 through the first motor 8;

[0046] S2. Start the second motor 41 and drive a plurality of support rods 45 to swing reciprocally through the second motor 41. When the support rods 45 swing reciprocally, the lower packing rod 48 can be driven to swing in a wavy shape; meanwhile, drive the aeration device to continuously aerate the inside of the mixing chamber 3 through the second motor 41 to increase the oxygen content of the sewage; while the aeration device is working, drive the push plate 50 to continuously move up and down reciprocally;

[0047] S3. The sewage enters through the first feed cylinder and flows out through the second feed cylinder. The trapezoidal frame 49 can filter a large amount of large particle debris. Then, during the process of the push plate 50 moving up and down reciprocally, the large particle debris is removed. The sewage entering the box body is agitated into a vortex by the scraper 7, fully mixed with the packing rod 48 and oxygen. The aggregated particles filtered by the filter plate 6 are crushed by the rotation of the scraper 7 and fully mixed with the packing rod 48 and oxygen under the mixing of the scraper 7, realizing sewage denitrification and decomposition of organic matters in the sewage.

Push plates that can move back and forth up and down are slidably connected to the inner sides of the sliding grooves. The bottoms of the multiple push plates are fixedly connected to each other. Whenever the push plate moves upward, the top of the push plate is flush with an adjacent plane, and multiple key-shaped holes are provided on the surface of the push plate.

4. The organic wastewater treatment device according to claim 1 is characterized in that: A reversing gear is meshed between the moving racks, and the reversing gear is fixedly connected to the inner wall of the shell. A driving device for controlling one of the piston rods to move up and down is arranged on the front side of the inflator.

5. The method for treating organic wastewater according to any one of claims 1 to 4, characterized in that: The following steps are involved: S1, start the first motor, and control the scraper to rotate synchronously on the surface of the filter plate through the first motor; S2, start the second motor, drive the multiple support rods to swing back and forth through the second motor, and drive the filler rods on the lower side to swing in a wave-like manner when the support rods swing back and forth; at the same time, drive the aeration device to continuously aerate the inside of the mixing chamber through the second motor to increase the oxygen content of the sewage; while the aeration device is working, drive the push plate to continuously move up and down; S3. Sewage enters through the first feed channel and flows out through the second feed channel. The ladder frame filters a large number of large particles of debris, and then removes the large particles of debris through the reciprocating up and down movement of the push plate. The sewage entering the box is stirred into a vortex by the scraper and fully mixed with the filler rods and oxygen. The aggregated particles filtered by the filter plate are crushed by the rotation of the scraper and fully mixed with the filler rods and oxygen under the mixing of the scraper, thereby achieving sewage denitrification and decomposition of organic matter in the sewage.
